Vladimir Kara-Muzra, a British-Russian dissident, received news that his mother has been hospitalized in Berlin while authorities are looking into a potential case of attempted murder.
Elena Gordon told doctors she “suspected she had been poisoned” and was sent to a hospital isolation ward as if she had been.
The German-Russian woman could be the latest victim in Vladimir Putin’s brutal campaign of assassinating opposition abroad.
Her son, Vladimir, was part of the prisoner swap in August after he was sentenced to 25 years in a Siberian prison on sham treason charges.
The journalist and opposition politician has been poisoned himself twice by Putin’s lethal spies.
Vladimir said in a post on X: “Thank you so much to everyone for your concern and well-wishes.
“My mother is indeed in a hospital in Berlin, but suspicions of poisoning or heart attack have thankfully not been confirmed.
“The doctors are continuing with the evaluation.”
An initial screening of Elena for toxins did not produce a result and there is “nothing to indicate a poison gas attack”, Bild reported.
But, as a precaution, doctors at Charité hospital are treating Elena as if she is severely poisoned.
Berlin cops said in a post on X they are “currently investigating the suspicion of attempted murder.”
They said: “A woman told medical staff at a clinic that she suspected she had been poisoned.
“The patient has been transferred to the Charité isolation ward.
“Blood tests for all types of toxic substances are carried out.
“All police measures required to safeguard public safety and to identify potential suspects are underway.”
Vladimir had previously been poisoned by the Russian tyrant’s goons as Putin has sought to silence dissidents abroad.
The 42-year-old was part of a dramatic Cold War-style prisoner swap that also saw Wall Street Journal reporter Evan Gershkovich freed.
Vladimir has vowed to return to Russia, telling the BBC: “I don’t just think, I don’t just believe, I know I will be back home in Russia.
“How could I have called on my fellow Russian citizens to stand up and resist the Putin dictatorship if I didn’t do it myself.”
He feared he was “to be shot or something” before the August prisoner swap.
Earlier, he told his family: “I was sure I was going to die in prison.”
In an emotional Oval Office call, Vladimir spoke to his family and Joe Biden as he was set to be released.
He said: “No word is strong enough for this.”
Vladimir was serving a horrific 25-year prison sentence for “treason” in a hellhole penal colony in Siberia.
He was arrested in April 2022 before being sentenced a year later in a “show trial”.
While in prison his health deteriorated and friends worried that he would “likely die”.
Vladimir, who grew up and studied in Britain, suffers from a nerve disorder after the two poisonings in 2015 and 2017 that he blames on the Kremlin.
Fears of a planned Russian assassination were ramped up when Vladimir’s ally Alexei Navalny was found dead inside his jail.
